protocol throughput

[Nathan W. Labadie]

Recently we've been conducting throughput tests on various protocols. The 
results of the protocols can be viewed at:

http://network.ucomm.wayne.edu/benchmark/

So... I guess the real question is this: is it possible for a single SMB file 
transfer to go faster than 20 Mbps? Is 20 Mbps as good as it gets?

We had done tests with 9x/NT4/2K and achieved similar results when TCP/IP is 
used as the transport. I've include the relevant [global] of my smb.conf 
files for both systems. I've also tried tweaking the SOCKET OPTIONS, but the 
largest increase I had seen was ~1.5 Mbps. Any help would be greatly 
appreciated.

Thanks much,
Nate
